This revision now requires changes to proceed.

This is an issue with LDG handling.  canLowerToLDG() is returning true for an i8 load zero-extended to i32, but SelectLDGLDU cannot handle this case.

I propose we fix SelectLDGLDU() [or the call-site in SelectLoad()] instead of working around this issue.
